This is fine.  Make Newmenulist a static (struct menulist *).  The call
to bind_BindList will effectively, (1) set up the proctable entries that
will be called when their associated menuitems are called, (2) add all
the menuitems described in the bind_Description to the menulist
Newmenulist.  The thing that is left out is that there has been no
association made between the Newmenulist and the view that will respond
to the menu choice.  The best way to do this is (1) create and
initialize a static menulist (Newmenulist) in InitializeClass.  You've
done this right; (2) after you've created the view that you want to
associate with these menu items, make a call to menulist_DuplicateML(). 
Here it is:

static struct menulist *Newmenulist;

static struct bind_Description Bindings[]={
        {NULL,NULL,0,"Quit",0,0,NULL,NULL},
        {"Insert-Strings",NULL,0,"New Menu Card,Insert Strings",0,0,InsStrings,
        "Insert Strings"},
        NULL
};

static void
InsStrings( txtv, rock )
struct textview *txtv;
long rock;
{
    printf(">InsStrings\n");
}

boolean
foo__InitializeClass(classID)
struct classheader *classID;
{
    struct classinfo *classinfo = class_Load("textview");
    Newmenulist = menulist_New();
    bind_BindList(Bindings,NULL,newmenulist,classinfo);
    return(TRUE);
}	

void opennewwindow()
{
    struct textview *newtextView;
    struct text *newtext;
    struct frame *frame;
    struct im *newim;

    newtext = text_New();
    newtextView = textview_New();

    view_SetDataObject((struct view *)newtextView,
	(struct dataobject *)newtext);


    menulist_ChainBeforeML(newtextView->menus,
	menulist_DuplicateML(Newmenulist,newtextView),0);
    
    frame = frame_New();
    newIM = im_Create(NULL);

    frame_SetView(frame,newtextView);
    im_SetView(newIM,frame);
}

Happy Reunification!
